Support Team Shaun_E Posted April 19, 2011 Support Team Share Posted April 19, 2011 It has been pointed out to me that my standard Caterham (Piper Cross?) airfilter might not be optimal for my new engine. What air filter is being used on a Bernard Scouse airbox for 240+bhp? It's an 80mm outlet and I haven't got time to modify it to 100mm as I believe some people have done. (Rolling road is on Thursday) K&N do some cone filters that look like they would fit but do they flow any better than the Piper Cross foam ones. Piper Cross sell a 150mm diamter 200mm long filter rated at over 300bhp but would this fit in the engine bay? Thoughts please. Link to comment Share on other sites More sharing options...
Racingshoe Posted April 19, 2011 Share Posted April 19, 2011 I use a K&N cone filter on my 'scouse airbox, although i'm only about 210bhp. It was recommended to me by Dave Jackson though who ran one on his 250bhp+ 1900k, so you should be alright. I just called Dave Kimberly at Demon Tweeks and he selected the right one for me.

Support Team Shaun_E Posted April 19, 2011 Author Support Team Share Posted April 19, 2011 Did it bolt straight on or did you need to make an adaptor from a bit of tube? Thanks, Shaun Link to comment Share on other sites More sharing options...
Jason Plato Posted April 19, 2011 Share Posted April 19, 2011 I made an adaptor with a section of drainpipe - photos on link below Link to comment Share on other sites More sharing options...
